A cheetah can run at a maximum speed
96.6 km/h and a gazelle can run at a maximum speed of 78.5 km/h.
If both animals are running at full speed,
with the gazelle 93.9 m ahead, how long before
the cheetah catches its prey?

  1. Vc = 96.6km/h = 96,600m/3600s = 26.8 m/s.
    Vg = 78.5km/ = 78,5 00m/3600s = 21.8 m/s.

    Dc = Dg.
    26.8*T = 93.9 + 21.8*T.
    T =
